Abstract

The aim of the invention is to develop a method allowing mercury to be determined in exhaust gases. All previously known methods for processing exhaust gases use wet chemical processes or thermocatalytic reactors, resulting in not inconsiderable secondary reactions of the components contained in the exhaust gases in addition to mercury. The aim of the invention is to develop a method which reliably converts Hg compounds into measurable Hg(el) without causing said secondary reactions in the presence of other flue gas components. Said aim is achieved by a low-temperature method that uses copper or copper alloys as a catalyst material for converting mercury compounds into elemental mercury. Red brass RG7 is particularly suitable, having the advantageous property of binding free halogens and thus preventing back reaction into mercury halides. Because of the low temperatures, said method prevents SO2 from being converted into SO3 while the metal surfaces of the measuring instrument are not additionally corroded. The test gas flows through an Hg converter in which the oxidized Hg compounds (e.g. HgCl2) are converted into elemental Hg with the help of the copper and other metals (Sn, Zn, Pb) contained in the red brass. The invention is used for determining exhaust gases in coal-fired power plants, waste incinerators, and cement factories.
